Optimization and Comparison of New Linear Permanent Magnet Vernier Machine

摘要

These days, vernier machine is one of the most popular structures of a permanent magnet machine for scientists in wave energy. Linear permanent magnet vernier machine (LPMVM) attracted the attention of the researchers, due to low cost for repair, easy maintenance and the ability to produced high torque in low speed. This paper proposes a new structure of linear permanent magnet vernier machine based on the existing machine. Proposed LPMVM analyses is based on the finite element method (FEM) in the variety of shape teeth with an integrated stator. Following that all models compared at the same size and condition. Finally, the best model is presented in terms of induced voltage, inductance, detent force and thrust force.
